Description:

[0001] The present invention relates to a method for the aggregation and
the transmission of multimedia data, in which method metadata is assigned
to multimedia data, a user profile is established utilizing user
information and multimedia data is transmitted from a central unit to a
communication device of a user. Particularly, the present invention
relates to a method for the aggregation and transmission of multimedia
data to various receiving devices of a user.

[0002] Currently worldwide, continually more computer and communications
systems are made to retrieve or transmit multimedia data over networks,
as for example a LAN (Local Area Network), a WAN (Wide Area Network) or
the Internet via for example the PSTN (Public Switched Telephone Network)
or a mobile radio network (PLMN: Public Land Mobile Network), for example
GSM network (Global System for Mobile Communication) or UMTS network
(Universal Mobile Telephone System) etc. Particularly, multimedia data
are displayed and/or edited and/or are made available to other modified
computer systems. Multimedia data include, among others, digital data
such as text, graphics, pictures, animations, video, Quicktime and sound
recordings. MPx (MP3) or MPEGx (MPEG7) standards, as defined by the
Moving Pictures Expert Group, also belong to multimedia data. The amount
of data arising from the transmission of multimedia data is, however, in
most cases enormous. Despite the strenuous efforts from the side of
industry toward to extension of the existing network, so far it is unable
to keep pace with the growing demand for more efficient networks and
greater transmission bandwidths. The situation has been contributed to,
in recent years, by the fast growing popularity of services such as the
Internet, the demand for multimedia "on demand", for example video films
or programs/data and network compatible multi-user games etc.
Consequently, greater numbers of users and larger amounts of data per
user are the triggers, bringing the network repeatedly to the limits of
capacity. Additionally, the costs for the use of the network are still
too high in comparison to the price of the retrieved multimedia data.
Belonging to the disadvantages for the extension of the existing network
is that such an extension is time consuming and proportionally expensive.
Attempts to carry the flood of data over other channels, as for example
broadcast systems (i.e. Digital Audio Broadcasting DAB or Digital Video
Broadcasting), over which broadcasters send unidirectional digital audio
respectively video programs (television programs) and digital data and
program associated data (Program Associated Data, PAD) to broadcast
receivers, have up until the present not been able to really break
through. A typical example of broadcasting is the carrying of controlled
access films over broadcast systems. The characteristic unidirectional
sending of these broadcast systems has, among others, the disadvantage
that especially the broadcasting by means of radio waves is lacking a
return channel from the broadcast receiver to the broadcast sender,
respectively to its operator. As a result of this missing return channel,
the possibilities for the settling of accounts for controlled access
programs and/or data are limited (for example to subscriptions). The
settling of accounts per subscription is, however, often not advantageous
for the user because the user is not able to spontaneously retrieve
controlled access programs and/or data for which they have not taken out
a subscription. A further disadvantage for the settling of accounts per
subscription is that the providers, respectively the operators of the
broadcast sender, obtain no direct information about which subscribed
services were also actually retrieved by the user. In the view of the
user the settling of accounts seems not to be a fair method of accounting
since they must pay for a subscription independent of whether they have
retrieved the subscribed services or not. Especially for operators of
small broadcast senders, respectively for small providers of controlled
access programs and/or data, the expenditure for the administration of
such subscriptions and for the settling of accounts of such services is
costly. However, one of the biggest disadvantages is that only very
imprecise data is available for the providers about the behaviour of the
user. This makes it difficult for the provider to adapt quickly to wishes
or changed behaviour of the user. In summary, it can be said that exact
statistical and individual data about the behaviour of the user and a
simple inexpensive system for settling of accounts via a reasonably
priced bi-directional network (interactivity user--multimedia provider)
is important and decisive for multimedia providers. These demands are not
satisfied by the state of the art in the required manner. The document
Mohan Rakesh, Smith John R. and Li chung-Sheng: Content Adaptation
Framework: Bringing the Internet to Information Appliances', GLOBECOM 99
shows a system, by means of which content adapted data can be transmitted
over the Internet to a user. With that the transmitted data quantity
allows itself to be reduced to the required amount. The European Patent
document EP 0905939 A2 likewise shows a system for reducing the amount of
data to be transmitted. The data could among others be coded and
compressed for this purpose by the system. The US patent document U.S.
Pat. No. 6,049,831 reveals a system, which adapts the data respectively
translates it into the proper format corresponding to the end device of
the user and the software used by the user. The system changes the
conditions corresponding to the end device of the user and thereby allows
the user to change the end device without problems. The international
patent publication WO 98/43177 of the prior art shows a system, which
chooses, extracts and specifically adapts dynamic data out of the
database, in which these data are transmitted to the user of the system.
The behavior of the user can thereby be captured and influence, if
necessary, the extraction behavior of the system.

[0003] It is an objective of the present invention to propose a new and
better method appropriate for the transmission of multimedia data.
Particularly, the settling of accounts for the retrieved multimedia data
and the recording of the behaviour of the user with an acceptable price
to performance ratio should be possible, the locating and the retrieving
of multimedia data be simplified for the user and the method should not
show the above cited disadvantages of the state of the art. A further
objective of the invention is to create an active push method for the
personalized aggregation of multimedia data by the system without the
user having to be active in the process in advance.

[0004] According to the invention, these objectives are achieved, in
particular, through the elements of the characterizing part of the
independent claims. Further advantageous embodiments follow moreover from
the dependent claims and from the specification.

[0005] In particular these objectives are attained through the invention
in that metadata is assigned to multimedia data, a user profile is
established utilizing user information and multimedia data utilizing the
assigned metadata and based on the user profile is selected, in which the
metadata is at least partially produced through automatic analysis of the
multimedia data based on the content of the multimedia data, in which the
user profile is generated at least partially, dynamically, from which
data of the user profile portions are able to be modified by the user,
and in which content oriented and optimized user specific multimedia data
is produced out of the said selected multimedia data by means of a
repackaging module in consideration of the data of the user profile,
which content oriented and user specific optimised multimedia data is
transmitted from a central unit to a communication device of the assigned
user of the user profile. In particular, the advantage of this invention
is that an optimisation of the transmission of multimedia is achieved
without the existing network having to be extended. This has the
advantage that the invention offers a more reasonably priced and faster
improvement without the user having to experience a reduction with regard
to the quality or quantity of the transmitted information. A further
advantage is the time intensive searching and compilation of the data, in
particular multimedia data, is much simplified for the user in larger
networks and the user is additionally able to receive a dynamic
preselection or summary established by the system (i.e. the user receives
for example active proposals for possible search actions from the system)
and an automation of the search directly influenced by the user.

[0006] In an embodiment variant the metadata is at least partially,
dynamically generated, in which the dynamic generation will be made at
least partially based on user data of the user profile. One of the
advantages of this embodiment variant is that the metadata is
continuously current as is necessary for the user. Additionally, this is
achieved without unnecessary consumption of system resources.

[0007] In an embodiment variant the user determines content oriented and
user specific optimized multimedia data and/or references to multimedia
data, which content oriented and user specific optimized multimedia data
and/or references to multimedia data (as for example hyperlinks) are
stored and made available in the database of the content module assigned
to the user. The embodiment variant has among others the advantage that
previously generated multimedia data must not be produced new each time
for multiple uses by the user. This allows for faster access to the
desired data with economy of the computing power. In particular, the
search for multimedia data utilizing the generated metadata utilizing the
defined, user specific references to multimedia data is enlarged.

[0008] In an embodiment variant the user manages the data that are stored
in the user assigned data store of the content module at least partially
himself. Management intends to refer to for example, in addition to the
direct access, the deleting or the editing of storage parameters. This
has among others the advantage that the user is able to directly
influence the storage of the data in the content module.

[0009] In an embodiment variant the user specific data about network
characteristics and/or data about hardware characteristics of the
communication device of the user and/or data about user behavior in the
user profile is stored. This embodiment variant has the same advantages
as the first embodiment variant.

[0010] In a further embodiment variant the repackaging module optimizes
the selected multimedia data in view of the user specific user data in
such a way that the data are fit to the demands of the communication
device of the user and/or the communication connection from the central
unit to the said communication device. This embodiment variant has
likewise the same advantages as the first embodiment variant.

[0011] In an embodiment variant content oriented and user specific
optimized multimedia for different communication devices of the user
stored is made available in the content module of the central unit of the
user. In particular, this is meaningful for embodiment variants where the
user is able to define several user profiles for different communication
devices. An advantage of this embodiment variant is that the user is able
therewith to manage centrally several completely different communication
devices. In that way he is able to, for example over a comfortable
interface of a computer system, determine and manage in the central unit
the multimedia data already delivered for one of a different kind of
communication device such as a WAP and/or SMS compatible mobile radio
device.

[0012] A further embodiment variant the user profile comprises access
conditions data, which stipulates the monetary value of a credit limit
definable by one of the user and/or the central unit, to which credit
limit an automatic billing of the retrieved, content oriented and user
specific optimized multimedia data takes place. This has among others the
advantage that with the recompense for access to the content oriented and
user specific optimized multimedia data the user or the central unit is
able to be freely define, as to which kind of accounting to which payment
amounts should be made.

[0013] In a further embodiment variant the central unit records automatic
and/or dynamic data about the user behaviour and stores them assigned to
the user profile. This has for example the advantage that statistical
inquiries about user behaviour are able to be carried out centrally and
multimedia providers are able to react quickly to changed user behaviour.

[0014] In an embodiment variant the user profile consists of fixed
reusable conditions data of the user and/or the central unit, based upon
which fixed reusable conditions data the central unit utilizes the user
profile and makes it accessible to a third party. This embodiment variant
has for example the advantage that the user can stipulate which level of
data about his user behaviour or his user profile may be made accessible
to a third party or may be used for statistical inquiries. For example,
the provider can then introduce a bonus system for such users who allow
more information about their user behaviour to be reused. Moreover, the
provider is also able to react flexibly to the client behaviour and
client wishes.

[0015] In an embodiment variant the user determines in advance the access
request data of the user data for the purchase of content oriented and
user specific optimized multimedia data, which access request data
comprises an identification of the desired multimedia data and/or user
specific details for the transmission of the desired multimedia data.
This has among others the same advantage as above in that the user
receives faster and more efficient access to the desired data (especially
access controlled data) for different communication devices.

[0016] In a further embodiment variant, the multimedia data comprises
programs (software) and/or program associated data. This embodiment
variant has for example the advantage that the appropriate processing and
display graphics programs or software for the content oriented and user
specific optimized multimedia data are able to be downloaded in advance
to the communication device of the user from the central unit.

[0017] In a further embodiment variant, the multimedia data comprises
hyperlinks.

[0018] An embodiment of the present invention will be described in the
following with reference to an example. The example of the embodiment is
illustrated by FIG. 1, which shows a schematic block diagram of the
method, in which multimedia data is personalized and user specifically
optimized through a central unit.

[0019] FIG. 1 shows an embodiment example according to the present
invention, in which embodiment example for the aggregation and the
transmission of multimedia data by means of a central unit 20 to a
communication unit 10 of a user multimedia data 52 is analyzed with
regard to its content and metadata 51 based on the content of the
multimedia data 52 is generated by the metadata extraction module 53,
respectively is aggregated in a personalized way. According to the
present invention the receiving device 10 is bi-directionally connected
with a central unit 20 over a communication network. The communication
network comprises for example a GSM or a UMTS network, or a satellite
based mobile radio network, and/or one of several fixed networks, for
example the public switched telephone network, the worldwide internet or
a suitable LAN (local area network) or WAN (wide area network).
Particularly, it also comprises an ISDN and an XDSL connection. Included
in multimedia data are to be understood among others digital data such as
text, graphics, pictures, cards, animation, moving pictures, video,
Quicktime, sound recordings, programs (software), program associated data
and hyperlinks or references to multimedia data. Also belonging are for
example MPx (MP3) or MPEGx (MPEG4 or 7) standards, as they are defined by
the moving picture expert group. The multimedia data 52 are able to be
stored accessibly at different locations in different networks or locally
for the central unit 20. The last named networks could include for
example a LAN (local area network) or a WAN (wide area network), the
Internet, broadcast cable networks, PSTN, PLMN or the like. The metadata
52 are extracted utilizing a content based indexing technique and are
able to include keywords, synonyms, references to multimedia data (e.g.
also hyperlinks), picture and/or sound sequences etc. Such systems are
known in the state of the art in diverse variations. Examples for this
are the US patent document U.S. Pat. No. 5,414,644, which describes a
three-file-indexing technique or the US patent document U.S. Pat. No.
5,210,868, which additionally also store synonyms as such-keywords during
the indexing of the multimedia data and the extraction of the metadata.
In the present embodiment variant, the metadata are able to be at least
partially produced dynamically (in real time) based upon user data of a
user profile 21. This has for example the advantage that the metadata is
always current and precise as useful for the user. There exists therefore
a type of feedback possibility about the user behaviour at the
communication device 10 to the metadata extraction module, which can
directly influence the extraction. It could be however that so called
agents are used particularly during the search for certain data. The said
user profile 21 is established utilizing user information and stored in
the central unit 20 assigned to the user. The central unit 20 generates
content oriented and user specific optimized multimedia data 52 according
to the user profile 21 and transmits it to the communication device 10 of
the user. The user profile 21 remains permanently stored assigned to a
particular user. The communication device 10 of the user can be for
example a PC (personal computer), TV, PDA (personal digital assistant) or
a mobile radio device (especially e.g. in combination with a broadcast
receiver). The user profile 21 can comprise information about a user such
as for example location of the communication unit 10 of the user in the
network, identity of the user, user specific network characteristics
2113, user specific hardware characteristics 2114, data about the user
behaviour 2112, etc. The user determines and/or modifies in advance of a
purchase of multimedia data 52 at least portions of the user data 211 of
the user profile 21. Naturally, he has equally the possibility to search
and to access multimedia data through direct access, without having
search and compilation help of the central unit in the network. The
remaining data of the user profile 21 are able to be determined
automatically by the central unit 20, by authorized third parties or
likewise the user. Thus, the central unit 20 can include for example
automatic connection recognition, user identification and/or automatic
recording and analysis of the user behaviour (time of access, frequency
of access, etc.). In an embodiment variant, these data about the user
behaviour are able to be modified anew then by the user corresponding to
his wishes. The multimedia data 51 are selected from the central unit 20
utilizing the assigned metadata 51 and based upon the user profile 21.
Content oriented and user specific optimized multimedia data are produced
subsequently from these said selected multimedia data 52 by means of a
repackaging module 30 in consideration of the user profile 21 and in
special cases the user data 211. For example, a user is interested in
stock market data (or a single portion of the stock market data), the
desired data are extracted from the general data found on the network,
are compiled and optimized corresponding to the user profile 21 for
example the user specific hardware characteristics 2114 or the network
characteristics 2113 (e.g. compressed, sequenced, picture resolution or
sound quality reduced). In an embodiment variant, the user has the
possibility to determine access request data 2111 in the user profile 21
before the purchase of the multimedia data 52. The access request data
2111 can consist of for example time, data, type, terms, general
descriptions (e.g. synonyms as well) and/or characteristics such as
resolution etc. of the desired multimedia data. Thus, the user specific
optimized and content oriented multimedia data are already supplied at
the point in time of the access by the user. So that the data of the user
profile for example regarding picture resolution are determined not only
by the central unit 20, but also are able to be at least partially
modified by the user (e.g. access request data 2111), special user wishes
(e.g. regarding download times) can be given attention during the
optimization. The above named process for the selection of multimedia
data and sequences of multimedia data according to the user profile 21 or
according to direct details of the user is understood under the
personalization of multimedia data. It comprises particularly a content
related compilation of data. The optimization to for example user
specific network and/or hardware characteristics and/or user behaviour
according to the user profile 21 is understood under user specific
optimization of multimedia data. In an embodiment possibility, the user
profile 21 consists of a credit limit 2115. The credit limit 2115 is one
of the user and/or the central unit 20 and/or third party (e.g. banks,
credit card companies, multimedia providers) definable monetary value and
stipulates a maximum monetary value for the purchase of content oriented
and user specific optimized multimedia data to be paid for, to which
monetary value an automatic billing for the purchase of multimedia data
is able to be carried out by the central unit 20. Upon exceeding the
credit limit 2115 a check is initiated from the central unit 20 for
example to the banking institution regarding the credit worthiness of the
user. The credit limit 2115 can also serve the user as a protection
against unforeseen costs for the purchase of multimedia data. In
particular, the user is also able to access through the billing from
third party providers access controlled multimedia data (conditional
access) to be paid for over the central unit 20. The handling and
management of the settling of accounts (billing) and/or access key are
carried out by the central unit 20. The encryption and/or decoding of the
access controlled multimedia data is achieved by means of an access
controlled module of the repackaging module 30, in which for example
distribution key and/or session key is able to be used according to the
ETSI standard. According to the invention, the repackaging module 30 is
able to be implemented by way of - hardware or software. For the billing
of the retrieved multimedia data, meaning the settling of accounts for
the purchase of the data, corresponding settling of accounts data are
generated by the central unit 20, which comprises for example receipts
for the settling of accounts (e.g. electronically signed), similar to CDR
receipts (call data records) with so called DUR receipts (DAB/DVB usage
records). The receipts for the settling of accounts are transmitted from
the central unit 20 for example to a clearing module of a credit card
company, where they are further processed, or the central unit carries
out the billing autonomously. The content oriented and user specific
optimized multimedia data can also be provided with an electronic stamp,
an electronic signature or an electronic watermark by means of the
repackaging module 30. The electronic signature allows the content
oriented and user specific optimized multimedia data to be assigned at
any future point in time to the user, who has retrieved it from the
central unit. The misuse of cost compulsory multimedia data can thereby
be prevented. Particularly, the user profile 21 can also comprise
reusable conditions data 2116, which are determinable by the user and/or
the central unit 20 and/or authorized third parties (as e.g. the provider
of multimedia data 52). Based upon the reusable conditions data 2116, the
data of the user profile 21 are analyzed and made accessible to third
parties (which can be in any case determined by the user or the central
unit 20). The user in this way determines the protection of the data. The
statistical analysis can be obtained generally as well as individually
for the specific user. The central unit 20 functions thereby as an
independent filter station for the data according to the reusable
conditions data 2116. In particular, the reusable conditions data 2116 in
combination with the billing allow bonus systems to be implemented based
upon the reusable conditions data 2116 by means of the central unit 21.
In this manner, for example the purchase fees for cost compulsory
multimedia data can be reduced by the provider, when the user sets the
reusable conditions data 2116 so that the provider is able to know more
about the specific user behaviour. This gives the provider many
advantages. In this manner he is able to react for example faster to
changed specific user behaviour as well as general trends and to take
these into consideration. Another application of this type of statistical
analysis of the present invention is the possibility for the system using
the said analysis to build communities or groups of users with the same
or similar interests. This allows for example an optimized and perhaps
more time and cost intensive aggregation of multimedia data through the
system. An opposite approach is, if the system notes statistically that
for example different users searched repeatedly and/or requested objects,
which were not able to be found. If multimedia data with the desired
content do not exist, it can be deduced that apparently a new interest or
a demand for multimedia data with currently still unavailable content
exists or a demand is in the process of developing. That allows the
content provider to react quickly to new interests and create a
respective market position for himself. The content oriented and user
specific optimized multimedia data are stored in a database 41 of a
content module 40 of the central unit 20 made available to the user. In
this database 41 is not only the central unit 20 utilizing the user
profile 21 able to store content oriented and user specific optimized
multimedia data and/or references to the content oriented and user
specific optimized multimedia data, but it also allows the user to store
content oriented and user specific optimized multimedia data and/or
references to the content oriented and user specific optimized multimedia
data in the database 41. Consequently, the user receives indirectly for
example via the access request data 2111 influence over the data already
in the database 41 and directly in that he determines the said data (e.g.
for multimedia data, which he intends to use at a later point in time).
This allows the user to further optimize his time of access. The user is
able to access the content oriented and user specific optimized data of
the database 41 of the content module 40 with the communication device at
any time or the central unit 20 carries out the download of the data to
the communication device 10 at a prearranged point in time. The
determination of the already compiled content oriented and user specific
optimized multimedia data can take place depending on user interface for
example with drag-and-drop or another selection mechanism. It can be
convenient to integrate an alarm function into the system, making the
user aware with the use of an alert, that important multimedia data would
have been compiled utilizing the profile, but this data could not or was
not able to be pushed by the system due to for example the choice of the
end device respectively the communication device 10 (meaning e.g. that
the multimedia viewed as important by the system do not comply with the
technical necessities of the communication device 10). As an additional
service, it can also be offered that upon the demands of the user the
content or specific parts (e.g. determinable by the user) of the content
of the database 41 of the content module 40 be stored on a physical
medium, such as for example CD-Rom or DVD and be delivered to the user
for example via the post.

[0020] It is important to point out, that the user has the possibility
according to the present invention to define for himself several
different user profiles 21 at the central unit 20 for different
communication devices 10 and/or different network locations etc. In so
doing he can define for example a user profile 21 for a mobile radio
device, a user profile 21 for a PC and one for a PDA. Since the different
user profiles 21 are each assigned to the same user, he is also able to
commonly modify and manage the user profile from his different
communication devices 10. In so doing he can determine access request
data 2111 during the day at his employment on his PC, in order to access
the multimedia data (stock market, weather, sport, etc.) according to the
predefined access request data 2111 later on the way home with his mobile
radio device. The central unit 20 functions as a central management
element, which allows the user to manage his different end devices and
the desired multimedia data in a convenient manner. Through this
reciprocal access, a widest possible optimization with most minimal
network load and greatest user comfort is achieved. Since the user
receives a permanently, assigned, stored user profile 21 in the central
unit 20, the central unit 20 also has the possibility to take into
consideration load peaks for the performance of calculation and/or
network transmission (time, transmission channel etc.). On the other
hand, it is important to note that with the present invention an active
from the system push-situation is created by the system for the user
without the user having to be active himself, meaning the data is
compiled by the system without further user intervention utilizing his
user profile 21 and if it is the planned case independently transmitted.
This can take into consideration as with automatic device recognition for
example the time of the user behaviour for different communication
devices (end devices) by the same user etc. It is also possible to
